I’m in my teens and I always talk to guys who have weird slang?

basically him and i were talking and he kept wanting to hangout with me and he said he’ll come pick me up and i told him i couldn’t and he was like “slide, i’m tryna get on some withcu” and i don’t know what he meant by that so i said another day and he said “ur not tryna get on some wimme or some” again so can someone explain to me what he possibly meant by that
